"No surprise that Apple's new Mac App Store has a similar set of rules and regulations as the iPhone App Store, and we just got the full list. There's nothing here that's too different from the iPhone review guidelines, but it all seems terribly odd when applied to a regular computer, and some of the more restrictive policies have already drawn ire from developers like Mozilla's Director of Firefox Mike Beltzner, who says the restriction against beta code won't work well with the Mozilla 'open beta' development process."

Chapter 2.16 states: "Apps that download or install additional code or resources to add functionality or change their primary purpose will be rejected."

A runtime exactly does "install additional code or resources to add functionality or change their primary purpose".

So, as far as I understand that rule: No runtimes.

I fail to see your logic here. Look at where the word "their" is in the clause, it clearly refers to the word "app". The implication being that if an application downloads code to change its behavior, i.e. say a word processor app downloads code to change it into a game app, then it will be most likely be rejected. An app that downloads plugins, like eclipse also might be rejected. But I see nothing here that says that an app can not use a runtime, be it a pre-installed runtime, or one that is delivered with the app.
